Packaged Oily Wastewater Treatment System

Mitsubishi Chemical Aqua Solutions’ DiaFellow DM provides the best solution
for various water treatment sites.

DiaFellow DM

Great for these uses:●Car wash wastewater treatment and recycling●Compressor drain treatment●Oil, power and steel plant wastewater treatment●Garage wastewater treatment and recycling●Degreasing and rinsing treatment●Factory rainwater and wastewater treatment●Coolant water treatment and recycling●Tank yard wastewater treatment●Other general mineral oil and oily wastewater treatment

Current oily wastewater treatment system lacks suﬃcient ability to remove oil in wastewater
Current oily wastewater treatment system requires too much treatment and maintenance

Packaged Oily Wastewater Treatment System

DiaFellow DM

Easy maintenanceReliable,stable treatment
The system removes not only oil,but also high rates of chemical oxygen
demand (COD) and suspended solids (SS),providing stable treated water quality.

With fully automated operation possible,
there is no need to replenish additives
or treat sludge.
Normal maintenance consists
only of adsorbent replacement
and equipment inspections,allowing for the reductionof maintenance costs.

Compact design
The system’s compact design
with few components allows
for lower facility costs
and smaller installation areas.

1. Easily achieves concentrations of 5mg/l or lower
with a powerful oil adsorbent.
The powerful DiaFellow DM oil adsorbent, developed by Mitsubishi Chemical, cuts surface oil,dispersed oil, emulsiﬁed oil and oil otherwise mixed in with wastewater. DiaFellow DM alsoenables you to remove oil emulsion, which has been diﬃcult to treat until this point.

Fully enclosed
The fully enclosed systemallows you to keep
the environment clean.

2. Recycles wastewater and cuts costs.
Water treated by the DiaFellow DM is exceedingly clear, allowing wastewater to berecycled. Expect signiﬁcant cost savings from water used for car washes and coolant.

Recycles wastewater

Handles highoil concentration

With no additives, treated water
can be recycled for a wide variety
of uses with DiaFellow DM
as a water recycling system.

Depending on the characteristicsof what is to be treated,various combinations of pretreatment
and post-treatment facilities
are possible.

Note: Generally, "oil" is represented as n-hexane extract. There are also "mineral oils," "plant and animal oil" and "non-oil components."
DiaFellow DM treats all but plant and animal oils.

The DiaFellow DM Oil Adsorbent
The DiaFellow DM is a powerful oil adsorbent
researched and developed by Mitsubishi Chemical.
A granular product comprised of a high molecularlipophilic polyoleﬁn compound and a mineralizedmaterial is loaded into the adsorption tower. The
product then passes through the oily wastewater andadsorbs the oil, removing it.
